About Us...


AIR DALLAS INSTRUMENTS, INC. FOUNDED IN 1977 at Dallas Love Field Airport, where we remained growing and serving the local & national aviation communities until April, 1998. The beginning of a new era in late 1997 business growth demanded a bigger and better facility. So the process began, we purchased land and meet with architects to design the facility. Shortly after, we broke ground and in April 1998 we moved into our new facility in Lewisville, TX. While the new facility is just north of the Dallas/Ft. Worth metroplex it offered the ability for growth and improvement.

Our reputation speaks for itself for those who have used our company for their service work and the repeated referrals that we receive from them. Quality workmanship, integrity, experience, competitive prices, every effort to accommodate requested delivery time, and the lasting relationship that we strive to build with our customers is the base of our business and what we represent. All work is performed on site by our highly skilled technicians.

Founders of Air Dallas Instruments


September 19, 1977 Wimber L. Clark and Mary Ann Clark founded Air Dallas Instruments.

Wimber joined the Navy in 1946 at the young age of 17.  He received his Navy training on instrumentation and aircraft wiring.  During this time, Wimber began to realize his true passion and ambition.  After he got out of the Navy, Wimber continued to work in the aviation and instrumentation field with various shops in the Houston, Texas area.  In 1964, he was hired by an instrument shop in Dallas, Texas. Wimber along with his wife, Mary Ann and their three daughters', moved to the Dallas/Ft. Worth area where he continued to work and build a solid reputation in the industry.  His growth continued as a shop supervisor for such companies as Omni Air, Aerosonic Corporation - Addison, Texas, and other facilities in the Dallas area.

In 1977, Wimber’s dream came true when he was able to open his own repair facility along with his wife, Mary Ann, who handled the front office and his son-in-law, Jerry Holton.  The following years brought more growth opportunities for both family and employees of Air Dallas Instruments.

Wimber passed away on April 2, 1989 leaving his wife, Mary Ann, along with family members, to continue running the company.  Since the passing of Wimber in 1989, she had become the President/CEO of Air Dallas Instruments for 18 years and made the family proud to have her continue their father’s legacy. Mary Ann passed away on October 1, 2007.

Today all three daughters', Cathy Barnfield President/CEO, Cynthia Holton Treasurer/Accts. Receivable, Linda McInis Secretary/Logistics Parts manger, two of their husbands’ Danny Barnfield Vice President/Shop supervisor and Jerry Holton Vice President/Quality Manager own and operate the company. Danny and Cathy’s son, Brent, also works as a technician at Air Dallas Instruments.  The family is determined that Air Dallas Instruments lives on and will continue to insure their parent’s dream for quality and customer’s satisfaction.
